A Last Design with Uniform Foot Pressure Free Form Deformation

Open publisher page 3 citations

Abstract

The human foot has different shapes according to sex and age. It is an essential factor to consider the individual foot shape and characteristics. The conventional last design method does not take care of these factors and it just depended on the method based on bare eyes and skilful hands. Those results in the last design are not proper for the human foot. To solve these problems the last end shoe has to be designed based on the 3dimension (3d) foot shape and foot pressure data. This paper presents a 3d last design system utilizing a Uniform Foot Pressure Free Form Deformation (UFPFFD). The proposed UFPFFD is operated on the rule of foot pressure unbalance analysis and FFD. The deformation factor of the UFPFFD is constructed on the FFD lattice with the foot pressure unbalance analysis on the measured 3d foot shape..
